Technical Field

The invention belongs to the technical field of agricultural bactericides, and relates to a binary compound bactericide composition, in particular to a composition containing flumorph and dimethomorph.

Background

Flumorph is a chemical substance, is easily soluble in acetone, ethyl acetate and the like, is stable to light and heat under normal conditions, is hydrolyzed slowly, belongs to morpholine agricultural bactericides, and is particularly effective on peronospora and phytophthora pathogens. Has bactericidal effect on Oomycetes, especially Peronosporaceae and Phytophthora on grape, potato and tomato.

The alkene oxime amine has wide bactericidal spectrum and high activity, has prevention and treatment effects, has good compatibility with environmental organisms, and can be used for preventing and treating various plant diseases such as wheat rust, wheat powdery mildew, rice sheath blight, false smut, cucumber powdery mildew, cucumber downy mildew, grape downy mildew, apple alternaria leaf spot, apple powdery mildew, banana leaf spot, tomato early blight, pear scab, strawberry powdery mildew, sunflower rust and the like.

The two pesticides have the functions of sterilization and treatment on downy mildew and early blight, but the sterilization and treatment effects are not obvious when the pesticides are used singly, and if the pesticides are used in a blending mode, whether the pesticides have the synergistic effect in different blending ratios is not obvious.

Therefore, the invention needs to seek a proper blending ratio of the fluorine-containing morpholine and the alkene oxime amine so as to optimize the sterilizing effect of the bactericide.

Disclosure of Invention

The invention aims to provide a composition containing fluorine morpholine and dimethomorph, and applications thereof, which improve the sterilization synergistic effect of the composition containing fluorine morpholine and dimethomorph and application thereof, and increase the sterilization effect.

In order to achieve the purpose, the invention adopts the following technical scheme:

a composition containing fluorine morpholine and alkene oxime amine is characterized in that: the composition comprises the following components in percentage by weight: the effective components comprise 1-50%, dispersant 5-20%, wetting agent 0.5-5%, thickener 0.5-5%, and carrier for supplementing 100% of dispersed oil suspending agent;

the effective components comprise: the relative proportion of the flumorph and the dimethomorph is 1-20:1-5 in percentage by weight based on the weight of the effective components.

Preferably, the relative proportion of the flumorph and the dimethomorph to the dimethomorph is 1:1 based on the weight of the effective components.

Further, the dispersant comprises one or a combination OF more OF SK-5935, SK-5110, SK-560EP, YUS-CH1100, YUS-110, YUS-EC2200, YUS-OD1200, YUS135B, YUS-EP60P, YUS-D935, SP-OF3468, SP-OF3472B, Greenmul EF68 and Atlox 4912.

Further, the wetting agent comprises one or more of agricultural milk 0201B, agricultural milk S-80, agricultural milk 500, span 80, agricultural milk 1601 and agricultural milk AEO-3.

Further, the thickener comprises one or two of organic bentonite and white carbon black.

Further, the carrier is one or more of methyl cellosolve, methyl oleate, ethyl oleate, vegetable oil or methylated vegetable oil.

An application of a composition containing flumorph and dimethomorph in preventing and treating tomato early blight and cucumber downy mildew.

Therefore, the technical effects achieved by the invention are as follows: the composition is mixed in a mixing tank, so that the effective components of flumorph and dimethomorph are uniformly dispersed, wetted, emulsified, sheared and sanded under the action of a dispersing agent and a wetting agent, and the effective components of flumorph and pyraoxystrobin are uniformly attached to a carrier under the action of a thickening agent to form a suspending agent;

compared with a single reagent, the mixed suspending agent has obvious synergistic effect, specifically has obviously enhanced cotoxicity coefficient, and improves the control effect of downy mildew.
